Why it matters?
EN 818-2 Sling Chain
Chain Slings & Lashing
Medium Tolerance
Designed for flexibility and hook attachment. NOT for powered hoists.
EN 818-7 Hoist Chain
Electric/Manual Hoists
Fine Tolerance (Calibrated)
Strict dimensions ensure the chain fits perfectly into the hoist's sprocket wheel without jamming.
Working Load Limit (WLL): Maximum load the chain is designed to sustain. Based on a 4:1 safety factor. Manufacturing Proof Force (MPF): Force applied during manufacture (2.5x WLL) to verify integrity. Minimum Breaking Load (MBL): Minimum force the chain must withstand before failure (4x WLL). Min elongation: 20%.

Chain Grade Guide
What is the Difference Between Welded Chain Grades?
🚫 Carbon Steel ChainGrades 30, 43, 70 Used for tie-downs, towing, and securement. NEVER used for overhead lifting.
✅ Alloy Steel ChainGrades 80, 100 Specifically designed and heat-treated for Overhead Lifting and Sling Assemblies.
How is "Grade" Calculated?
The grade number represents the chain's tensile strength (mean stress value). It is calculated by dividing the tensile force (Newtons) by the cross-sectional area of the two links ($mm^2$).
As the Grade Increases:
The material becomes harder and more resistant to abrasion.
The Strength-to-Weight ratio increases (more lifting power, less weight).
The Working Load Limit (WLL) increases significantly.
Towing, general utility, load securement. Stronger than G30.
NO
Grade 70 (Transport)
Heat-Treated Carbon
Heavy Duty Securement. Standard for trucking tie-downs. Identified by Gold/Yellow finish.
NO
Grade 80 (Alloy)
Alloy Steel
Standard Lifting Slings. High ductility (stretch) to absorb shock.
YES
Grade 100 (Premium)
Alloy Steel
Heavy Lifting. 25% stronger than G80. Harder surface for abrasion resistance.
YES
Common Problems & Critical Safety Warnings
Even with the correct grade, misuse can lead to catastrophic failure. Ensure your riggers are trained to avoid these three common hazards:
⚠️ 1. The Hoist Chain Trap
A frequent and dangerous mistake is using the load chain inside a hoist to wrap around a load.
The Design: Hoist load chain is hardened specifically to fit internal sprockets (tight tolerances). It lacks the ductility (stretch) required for a sling.
The Risk: Wrapping it around a load deforms the links. When retracted, the deformed links can snap or destroy the internal hoist mechanism.
⚠️ 2. The "Gold Chain" Error
Using Grade 70 (Gold) chain for overhead lifting is a common error because the chain looks robust.
Why it Fails: Grade 70 is heat-treated for abrasion resistance (for rubbing against truck beds), not for the elongation needed to absorb the dynamic shock of a crane lift. It may snap suddenly without warning.
⚠️ 3. General Neglect
Alloy chain is tough, but not invincible. Proper storage and inspection are vital.
Corrosion: Leaving chain on damp shop floors promotes pitting and stress corrosion cracking.
Inspection: Chains must be inspected regularly for nicks, gouges, and elongation (stretching).
